Oblique line patterns in clothing exhibited a three-factor image structure which was fundamentally similar to that described in the first report (vertical-horizontal patterns). The influence of each factor was also very similar, and in addition to clear evidence of the strong influence of thickness of line and line color, an interactive effect between the two was also seen. Orientation of oblique line did not seem to have any direct connection with the impression produced.

This paper aims to clarify the best character composition for the body of the newspaper. First, an experiment on readability of 15 samples, prepared by the combinations of the number of characters per line and linespacing, was carried out. The obtained data was analized by the theory of Hayashi's Quantification (1) together with the data from the experiment changing the size of the character, to seek the correlation between the number of reading characters and the 3 factors, i. a, size of character, number of character per line and linespacing. Second, an investigation on the visual impression of these samples was made by means of Semantic Differential Method to clarify the best combination of the 3 factors that yield the best impression. Taking additionally into account the findings up to now, it may be concluded that the character "new N type" (Asahi Shimbun Publishing Co.) of 108% and the composition of 20 characters per line and 1/2 linespacing is the best combination for the body.

The purpose of this study is to examine the design process in Japanese garden making, in which conceptual keywords such as ariyo, yo, omohaeru, manebi, ikanimo play an important role. In this study the roles of these keywords are investigated. Ariyo gives an ideal image of the garden as a general concept underlying yo, more concrete image of gardens. Ariyo means what the garden should be like, i. e., actual landscapes of mountains and water, and celebrated localities. There is an unwritten rule that designers should omohaete (recall) ariyo in reality, and attempt to manebi (imitate) them in disigning as a part of creative process. Size of a site and functions of houses in a garden are restrained naturally by the particular situation in realization of design, but it is necessary that the resulting garden must be ikanimo (just like) an actual place. In this way ariyo fruits in various garden designs. This kind of design process characterizes not only Japanese garden making but Japanese art as a whole.

Now, the personal computer has been introduced into school education, and the various kinds of educational usages of the personal computer are being adopted. But, it seems that the design education by the personal computer has not always been pushed. In such a situation, I have developed the color separation system for the computer graphics. By making use of it, I have had graphic design education and in it I let the students to print the image of computer graphics by silk screen process. This paper discusses the outline and the usage of the color separation system. As a result, the educational meaning was ascertained as follows: 1) It is useful in fundamental education of colors printing using silk screen process and of the color study, and in management of color planning. 2) It expedites learning on technical education for information processing as a part of design education and using the personal computer as the medium of "Design Work".
